Fabrication of Sn-Ni alloy film anode for Li-ion batteries by electrochemical deposition

摘要：

Sn-Ni alloy films for Li-ion batteries were fabricated by electrochemical deposition with rough copper foils as current collectors.The influence of electrochemical-deposition temperature and heat treatment were also investigated.By galvanostatic cell cycling the film anodes can deliver a steady specific capacity.The morphological changes cause the differences in capacity retention.After farther heat treatment,the film anodes present a better cycle performance,with a specific capacity of 314 mA-h/g after 100 cycles.This high capacity retention can be due to its smooth,compact surface formed in the heat treatment process.
